Every rival every Gloucester star had growing up, that's who they will face at Bath on Friday night.
Scrum-half Dan Robson tells the Cherry and Whites to channel the foes of childhood into the old enemy.
THE grinding axes never stop; they only grow, and sharpen.
The grudges start in childhood, then they escalate and intensify.
Victories build pride, defeats heap up despair.
Welcome to the time-honoured battle for the right to brag.
Two titans from opposite ends of the A46, characterised by apposite social stereotyping, will collide on Friday, in all muscle-flexing, sinew-twisting glory.
Neither house of history and tradition would have it any other way.
Each stable will argue this rivalry has no equal, citing wrongs of aeons past.
Dan Robson is not about to disagree.
The accomplished young Gloucester scrum-half relishes the unique, infectious West Country derby fever.
The 20-year-old pledged the newer Cherry and Whites will heed in earnest the history lectures that Kingsholm's stalwart professors like Andy Hazell and Pete Buxton will deliver this week.
But the Stoke-on-Trent born half-back said each individual must bring his own personal derby confrontation to The Recreation Ground table on Friday (kick-off 8pm).
Just as Southlander Jimmy Cowan grew up trying to get one over Otago, or Billy Twelvetrees once dreamt of sinking Northampton Saints, so the homespun Gloucester boys have long since tried to best Bath's aristocrats.
Everyone has their sharpening axe, their growing grudge.
Twice a year Newcastle-under-Lyme School pupil Robson used to leap out of bed with the same single thought: St Joseph's College.
Raise the standard and the intensity follows with it, believes Robson, but wherever, whoever and whatever, he reckons derby desire is the same the world over.
"You play for Gloucester, you know all about the Gloucester-Bath derby, no matter who you are or where you've come from," said the England Under-20s graduate.
"Jimmy's debut for Gloucester was our 16-10 league victory against Bath at Kingsholm back in October, and he was just so up for it.
"He's a competitor, he's up for every game, but there's just something extra about Gloucester-Bath.
"You'll have Andy Hazell in that changing room, screaming everything and going at you, and you can't help but be gripped by that.
"You always have derbies growing up for school or your local club anyway, and it's just a bigger version of that really.
"You know what to expect, and you enjoy it, because that's what rugby's about. Playing in front of a packed crowd, and trying to perform your best.
"I think we were on the wrong side of some of those games against St Joseph's, but we won a couple too.
"You wake up in the morning, and the first thing that comes into your mind is that you're playing St Joseph's.
"You can't wait to get out there, and try to claim those bragging rights.
"It's no different when you play Bath. It's all you think about, all week, when you go to bed or you get up in the morning, or people stop you in the street and tell you you've got to win.
"It's really important for us, simply as another in the long list of league games we really need to win.
"But throw in the derby spice and it just adds that little bit extra."
Just three weeks ago Gloucester suffered their heaviest professional-era Kingsholm defeat to Bath, 32-5 in the LV=Cup.
Forget the Anglo-Welsh Cup sideshow nature, this was full-tilt derby fury.
Victory at The Rec on Friday can cauterise the still weeping wound.
But it can also turn three reasonable weeks into a fine month.
The last-gasp 29-23 victory over Worcester on Friday leaves Gloucester with ten league points from three Premiership clashes – and that despite the 33-29 defeat at Wasps.
Add a triumph in Bath to the 27-11 win at Northampton, and Nigel Davies men will head into a two-week fixture break as credible play-off contenders.
Robson said: "We've targeted this group of four, and we need results away from home.
"It's a huge game for the club, the big local derby.
"And we've got something to prove as well.
"They came here recently and routed us a bit, they put us to the sword.
"And we don't like that, so we've got to go there and put a real fight and test them.
"We've just got to keep putting pressure on other teams.
"We've got to keep the points ticking over.
"If we keep putting other teams under pressure, they will crack, lose games and that will hopefully be our chance."
Gloucester failed to find fluency against Worcester, and were saved by the last-play penalty try after Errie Claassens tripped the likely whitewash-bound Jonny May.
Boss Davies said Gloucester reverted to chaos to clamber out of the mire, but Robson admitted the Kingsholm men cannot expect the tactic to pay off at Bath.
He said: "We needed to get a win, however it came, so it was important to get back to that at home.
"We are slightly disappointed with parts of our game, but you take results how they come.
"It was a bit weird being sat in the changing rooms, it was quite flat in there.
"But that says a lot about the standards we set ourselves, and we will demand more against Bath."
